Chaviva7, this may be a stupid question, but I'll risk it. Are you sure that when you raised the roof that the entire edge of it all the way across settled into the "notch" for it? I've discovered with our A213 that the side of the roof with the actuator goes right in, but I have to give the starboard side of it a little extra push by hand to get it in the notch all the way across. If the back part of the roof is not all settled into the notch on the front roof, that would leave room for water to be blown inside. Just a thought.
